New York City Police Commissioner Raymond Kelly says officers are examining ways to search the internet to track gunmen before they open fire on dozens of people.
Kelly said Friday that officers would use chat rooms to try and identify possible gunmen. They discussed the possibility of creating an algorithm that would enable officers to search terms commonly-used by people who are about to commit a mass shooting.
The ideas come a week after 26 people were killed in Newtown, Conn. Gunman Adam Lanza opened fire in a school, killing mostly young children. He also killed his mother and himself.
Kelly says officers would use publicly-available sites, engage the potential shooter online, and intervene to disrupt his plans. NYPD officials are working out details.
